Short summary
Establishing an etching procedure for monazite fission tracks (MFTs) is essential for MFT dating. In this short communication, we investigated the parameters governing the etching rate of MFTs, particularly the effect of radiation damage. Our results show an inverse relationship between MFT etching time and the degree of radiation damage. We show that existing etching recipes may not sufficiently etch MFTs in young monazite, advocating the importance of revising etching methods.
